STItEET AND STATION INDICATOR;

Application filed .Tune 1,

sengers as to the stopping places in advance,

so that there may be no uncertainty as to when they should leave-thecar.

A further object is to do this by means 10 which are sufiicien'tlyflexible and reliable in design to adapt the device to the variableconditions of the route followed. Other objects will appear from a studyof thespecifi cation. a a a Our invention comprisesan electricallyactuated mechanism for advancing a web hav-- ing the street or stationnames thereon, and means whereby such actuating means are started byhand and are automatically bringingthe new name into view. p i a Thefeatures of' our inventionswhich are believed to be new, and uponwhichpatent is desired, will be specifically defined by the i claim. n

In the accompanying drawings we have shown ourinvention in a form ofconstruction adapted to illustrate-the principles embodied, in which,however, many of the de tailed parts are shownlin simple-types ofconstruc'tion, for which other designs may be substituted withoutchanging their essential functions or their relationship in the combi-'nationsf Figure 1 is a plan view of the mechanism employed, except thatthe name-holding web has been omitted in order to clearly show theoperating mechanism. 1 c Figure 2 is a transversesectional elevationtaken at one end of the rollers,the plane being approximately indicatedby the broken line 2Q of Figure-1. 1 m a Figure 3 is a;wiringdiagra m.

Figure 4 illustrates control switch 48 and I its connected partsemployed in securing and controlling the periodicadvance of the namebearing web. The plane of view is indicated by the broken line 4-4 ofFigure 1.

Figure 5 is a'section taken on the plane in- 50 dicated by the brokenline 5-5 of Figure 11. 1 To display the street or station name, weemploy a web 11, shown in, Figure 2 but omitted in Figure 1. The ends ofthis web are secured to rollers 1 and 10 which are intermittentlyoperated to advance the web a single name space at'a time, and toreverse ers, through 1926; Serial No. 112,863.

ends of the web are reached. The means for actuating the web ispreferably a small motor of some kind. An electric motor 2 has beenshoWnfor doingthis. s

, The motor shaft 20 is connected-with the web carrying rollers 1-andlOibygear trains, these as illustrated comprising the gears andpinions numbered from 21to 27 inclusive. The gears 26 and 27, which arethe final gears of the trains, are mounted loosely upon the shafts ofthe rollers 1 and 10. They are each in turn, secured to turn withsaidrollclutch mechanisms. Said clutch mechanisms as shown each consistsof the direction of movement-of the web as the an arm, 3 carried upon asleeve30 which is 1 mounted upon the roll shaft .to turn ,there- Thelever 31 is areversin'glever andisac-1 V tuated to shift the engagementof the clutches, only when the direction ,of feed of i i the web is tobe reversed. Normally this would bejonly a'tthe ends of the run of thecar and as the ends ofthe webs are reached. The means adopted forsecuringsuch reversal will be later described.

The web 11,;-between, the storagerolls and 10, passes over guiderolls,,12 .a11d13,

which position that part of theweb; carrying the name to be displayedbehind a win-i One'of these guide rollers, 135as shown, carries twoelectrical conductorsin V the form ofv bars '14 andf15, which extendslengthwise of the periphery o'fthe r ller, and-overlap each-other at one"end, vThey are alsoangularlyseparated a small. amou t, i

This condition is clearly shown in Figures 1and2, p The machine is, tobeplaced in astreet-car,

,motorbus, or railroadfcar wh-ere it-can best be seen by the passengers,and is operated in the following manner Push button 57, which may belocated in i convenient place for the conductor ormotorman to press,is'pressed by conductor as each street or statlon 1s a proached, whichener gizes starting solenoi 52, which pulls plung-Y erand' closes switch42, giving energy to the motor circuit and at suitable and later times'to the stopping and reversing circuits.

When push-button 57 is pressed the curswitch .6,breaking the circuit ofthe stoppmg rent of electricity flows 10111 power line 50 throughconductor 56 and small solenoid '55,

which causes core 58 of the latter to open solenoid 53, coming fromswitches 14 and 15. Solenoids 55 and 52 are connected series byconductor 54.

When pushbutton 57 'is pressed and closes I switch 42 the motor, throughthe gear mech- 'anisin, causes the spools 1' which: hold the web '11carrying the street names, to revolve and wind oit one on totheothen'ov-er V the guide rolls 1213, bringing the street 1 names intofull View of passengers through glassil 1 When the we'b advances farenough to show the sweet: name proper-11y the motor is stoppedautomatically by contacts or switches 1-4-15onguide ro'll (Figure 2)coming in contact with common circuit 40 and 4 01' 41 (Figure 3) whichenergizes stopping sole- ;noid 53, which causes plunger to open switch42 which turns electric current off entire machine; Contacts i l-15 maybe adjusted closer or farther apart as'necessary. (lontact 14will bridge4 and while web is traveling in one direct-ion, and con-tact 15 willbridge 41 and 40 while'the web is traveling in the opposite direction."This is to properly regulate the stopping 'Of the "web.

- When the contact 14 comes in con-tact'i' vith 4 4O the current fiowsthroug'h 7240 and 14 to 75, 82,48, 61 to stopping solenoid 53. Contact15 would function with the web moving in the opposite directiont hroughnoid 53; 48-connects with '82':.throu-gh to'14 for one direction and 82'throughto 15 for V the other direction. :48 is controlled by thereversing plunger sl1alft'"8'3.

v 'Rever-sin'gis controlled by levers 171 7 one operated by spool 1 andone by spool 10.

V 7 Each web-receiving roll is provided with a Qrecess 16 and the lever1'7provided' with'a disk roller 18, positioned to drop into the recess16 which is uncoveredwhen the web 11 r is entirely 'unrolled from onespool Eor the other. When disk .18" drops. into recessfiti, lever 17makes contact with contactpoint' i9, completing the circuit which-energizes reversing solenoids 8 or -80v'vhic'hhave-a com-' mon plunger83. The extension of 83is connected with a pivoted lever 76 and this bya link 46 with theprojecting end '33 ot'aleve'r i 1 31' pivoted at 82and connecteclswith' the thereby close the circuit sleeves 30 whichcarry the clutch fingers 3. In this way the drive may be shifted fromoneof the rolls 1 and 10 to the other, and as the web is wound uponthese rolls in the "same direction and both turn in'the same di 52.;ancl53 and 55, are of iron the length'of the solenoids, and extensionsare-of brass.

47 is nonconducting material clamped to 83 holding sliding switch 48,which is con nected through '61 to stopping solenoid 53.

' 48 makes alternate contacts with 82 and 82 to complete the stoppingcircuit through 74 and 75 to contacts 14 and15to 40. What we claim asour invention is:
